IMPROVEMENT IN MACHINES FOR CUTTING S TAVES.

The Schedule referred to in these Letters Patent and making part of the name.

To all whom it may concern:

Be it known that 1, WILLIAM SissoN, of Fulton, in the county of Oswego and State of New York, have invented a new and improved Construction of Stave-Machines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing making part of this specification- Figure 1 being a-front elevation of the machine.

Figure 2, a side elevation thereof.

Figure 3, a vertical section of the same in a plane cutting from front to rear.

Like letters designate corresponding parts in all of the figures.

This invention is for a machine for cutting staves, having a stationary knife, A, and vibratory bed B, on which the blocks rest, and by which they are brought to the knife, and the staves thereby are cut from them.

For the present improvement the'frame O has two uprightstandards, a a, extending upward at the sides, in which the driving-shaft D is mounted at the top; and on this shaft are the balance-wheels E E, so that all the machinery is mounted in the one frame.

Two driving-cranks, G G, one at each-end of the shaft D, operate the vibratory bed B through connecting-rods H H, extending nearly vertically downward thereto, at the sides of the frame.

The result of this construction is that the machine occupies-the least possible room that all the wear of the connections is at the top and bottom of the crankbearings 12 b, in which the connecting-rods are adjustable in length; that the bed B constantly hangs sus-- pended by the connecting-rods, so that there is never any slack or loose movement, and consequently, little orno trembling or jarring of the machine, nor

purpose hereinspecified. 7
